[Q] Downgrading from 2.3.4 help! - myTouch 4G Q&A, Help & Troubleshooting

Well I picked up a mytouch 4g, but I want to root it or would rather just keep my phone..
So both guides in the xda forums haven't worked for me, one says you need temp root. Which I don't have. And another one says I need to use adb. Which I can't ever get installed on my computer, I've tried sooo many times..
Is there anyone out there that can help me?
Or another guide that's easier to just downgrade from gingerbread to froyo so I can root?
Thanks in advance.. and I've tried searchin and have found nothing...

Rooting a phone is technically exploiting a security flaw, or series or flaws. Since 2.3.4 is pretty much bullet proof on our phone you need to downgrade first. If you cannot get that to happen. Sorry about your luck.

You have to use adb. I never used adb before but I got it set up last night and downgraded to 2.2.1 without any problems. I read something about a goldcard method mentioned, but I have no idea what it is and how it works. Its worth a search though..

Rooting the G2? A little help kinda confused with things.

Hey guys ill be joining this side of the forums now on monday and I'm really excited. Just I'm kinda confused about a few things and I was wondering if anyone could help enlighten a few things for me.
I know what Root is, S-off, Cid yada yada and I'm not new to rooting at all. I have adb and etc and I kinda want to do this on ubuntu because my vista is kind of janky at times.
Now apparently there is Temporary Root and Permanent Root and of course I want Permanent root, s-off, etc.
1.Now from what I read there has been apparently an update that updated the G2 to 1.22 or something like that? I read its rootable apparently but you need a windows application called gfree or something? Is this possible to do using just ubuntu?
2. Now to obtain root, s-off etc do I have to obtain temporary root first, then permanent root? Its kinda confusing coming in a noob to this device and trying to figure this all out. And do the methods vary with which firmwire your phone comes with? I'm assuming mines will come with the newest OTA since I'm receiving it Monday.
3. Also from what I'm seeing apparently having S-off and root and what not matters on what rom your running also? I don't want to flash a rom then end up loosing root or something. And Noo I DO NOT want to stay stock once I obtain root. I'm kind of a flashoholic.
Thanks to anyone willing to help I really appreciate it.

Shouldn't yall warn him about using VISIONary first? SOMETIMES, no NOT all the time but SOMETIMES people get stuck in a boot loop from using the VISIONary method. I would not recommended it, if you have know how to use ADB, use it. I'm pretty sure that they have ADB for Linux because they do have the Android SDK on Linux(at least I think they do). All you need to do in order to root with the safer/recommended way is ADB. All you have to do is ADB Push some files to your phone then run them on your phone's Terminal Emulator App, its pretty simple. Though I have not personally rooted a G2 yet(I get mine tomorrow) but I have spent at least a week learning about how to root the G2.
Check out the wiki, explains how to root using rage+gfree.

I followed these instructions and rooted my phone fairly easily.

First of all follow the link I gave him, did you bother to do that, there was a warning, second of all I've helped a lot of people root following the videos and have had zero bricks as long as they do everything I posted in the link, third I rooted this way with zero problems, when people brick their phones its not visionary that bricks phones it people that think they know how to properly use visionary when they don't that bricks phones, its not just pressing the " attempt perm root" button to root your phone, you have to press certain settings in order to use it right.

You may be right, but all the bricks that I have seen on this forum are from people using the VISIONary app. I haven't seen a single person brick using the Rage and GFree method.

Alright and how would one fix a boot loop caused by Rage and GFree? I have searched before but I never found anything on it.
EDIT: And if you could, please show me some links with people stuck in a boot loop caused by Rage and GFree, I would like to read it and learn from their mistakes so that I don't do them.

hey david279, which radio(bandbase) did you have on your new G2 when you rooted with GFree?
Hmm just to make shure. I obtain root first, then use that gfree app on my rooted vision to get sim unlock, s-off etc?
Never mind just read it. This is actually really simple. *facepalm* sorry guys for the thread space ill get my topic removed.
I had the 26.03.02.26. I updated it to the newest one in the radio thread in the dev forum. I gotta use to those long radio version numbers.

Thanks, just confirming that 26.03.02.26 was still rootable with the wiki root instructions, there seems to be some confusion about if you can still root the 26.03.02.26 radio with the wiki, and you just confirmed that you still can.
Thanks Again, and happy flashing.
Rooting this phone reminded me of when I had a hero. That simple. I got a evo too and that was something to root when it first was released.

Exactly the info I was looking for I will be rooting later today.

odd issues after trying gfree

im attempting to root my mytouch 4g, got it brand new today
i have been able to root 2 in the past with no difficulty but for some reason when i try and root im not successful.
right when i enter
"./gfree -f"
i get
"error reading input file"
any help would really be appreciated
i tried searching but couldnt find anything..
i was able to downgrade from 2.2.1 to 2.2
after trying to gfree, still not rooted and i cant get s-off
any advice?
Although im at 2.2 now my hboot is 86.0
Is this ok?
still no root,
i wonder if visionary permanently messed up my file system...
what sucks is that my wifi doesnt work now since i downgraded to 2.2....

all of the how to's are exactly the same. just different information in each one.
I unrooted my phone and followed This Walk-though and it worked perfectly. no if/ands/buts about it.
If that seems to complicated you can always follow The Unlockr's method it's REALLY simple and easy to follow.

After following that procedure, you'll have the 0.85.2007 bootloader. The version number is lower, but it's actually better because it's the engineering version.

You really shouldn't post your email or your phone number on here... but try using the visionary method mentioned above
Sent from my HTC Glaciee using XDA Premium App
i tried that method right and now and it still said s-on :/
Visionary ROOTS the phone.
S-OFF means UNLOCKED BOOTLOADER.
Please read and understand the big difference between the 2. There is a ton of info, both on the forum and in Google. And if you don't understand - please refrain from messing with your phone.

All I can say is you're not following it correctly. Dozens upon dozens (or more) have used these guides with no problem, so if it's not working, the only other variable is user error. Plus, you didn't tell us anything about what's not working, so how could anyone help?

yeah, i just got a new mytouch 4g last week as well, and though i've rooted it with visionary, it won't stay rooted and s still =on. i can't get s=off. i've tried the gfree method, http://forum.xda-developers.com/showthread.php?t=858021, this one, (and the sdk adb one also)
and one prooblem i might be having, is i don't know what you mean when you say reboot or rather, i don't know if your saying to restart the phone or power off completely, or remove the battery, i'm really confused about your specific language.
thanks.

I'll ask in a simpler fashion i guess.
1) we know you've previously rooted your phone
2) we know you are now only keeping s-on.
What errors are you getting when you try to do the ./gfree method or the root.sh method..
if they are not working you are getting errors. What are they.
I dont want to use gfree since I see a lot of newbies having problems unrooting
Sent from my HTC Glacier using Tapatalk
nevermind...
so, i used gfree correctly this time i guess, it worked quite brilliantly. sorry for the noob-ness.
There is a method in the development section stating how to do because I have the 86. Bootloader and the gfree works fine for me

Rooting New Gingerbread release

Well it is now official that gingerbread has been leak/released for our G2 and I'm sure lot of us who had soft bricks are happy to know we can unbrick it and now to our next problem rooting it
I have tried 2 ways so far first is the wiki way with psneutur and gfree, and other is temp root with visionary
My results for both came negative,
Gfree/ psneutur gave me permission denied after I pushed it in
Visionary jus gave me black screen
And gingerbreak requirs s-off
So let's gather info and or figure out a way to root new gingerbread if any tried downgrade method let all us know with steps what you did
Here is the info for new gingerbread
Ship s-on
Hboot 0.82.0008
Radio 26.08.04.30M3
eMMC-boot
Apr 13 2011,
So hope we can find solution to root and we can get custom roms back on it
you need to try to gain temproot with gingerbreak. can you please come over #g2root ?
I just said I tempted and it just stuck on trying to root nothing happen and I will go what irc server? Freenode?

Visionary (as evidence by the sticky at the top of the dev phone saying DONT USE VISIONARY TO PERM ROOT) has bricked many a phones that have only now been able to be fixed. I think its just a trust issue and comes to down to each individual and what they personally think and believe I personally would never use visionary again no matter how many times its updated or "fixed". The trust has been broken.
Idk why there's hate on visionary... I rooted my phone the second day the process was released and I've never had an issue since...? And I've rooted 2 other g2s well after and still never had any issues... just followed instructions. I understand it can brick your phone, but then again... was it really visionary that bricked it? Or was it an user error placing blame?? Just saying....
Sent from my HTC Desire Z/G2 using XDA App
yeah i rooted my g2 using the visionary method and have had no issues. and it seems like a lot of the bricking has occurred since i rooted, so i dont get it.
i did visionary root with success, but put yourself in the other end of ppls shoes who did use visinary an you get a brick and no way out of it, other than have gfree with jus pushing, and everythign else is done for you, i would go that route than a higher chance of bricking,
But this thread is not bout bricking this is about how to obtain root on the new stock rom that is out
Yes please! if anyone finds out how to root the G2 with stock Gingerbread could you please post! thanks in advance!

user error? lol in a one-click root... maybe they were pressing the top right corner of the button and that's their error lol
I don't know, either, but there has to be some reasonable explanation, doesn't there? After all, many people (myself included) had no trouble rooting with Visionary. OTOH, this is my second G2 - the first went back under warranty. With the first one, Visionary was unsuccessful at perm-rooting. This one, worked on the first try. Odd? Computers are NOT supposed to behave randomly - so why the difference?
when someone comes up with the visionary source, there are people that can understand it. until then it's a black box.
+1
I'm in the same boat. I just got a brand new G2 off craigslist, and was very happy to see that it had gingerbread. But to my extreme dissappointment, I cannot root it or downgrade it to gain root. Below are the things I have tried and didnt work.
Visionary
Gingerbreak (v1,0, 1.1, 1.2)
Rage
Super One-click
Z4Root
Androot
Gold card, for downgrading, also tried Gold card with above root methods.
I have also tried taking the stock Froyo PC10IMG and modified the info txt to read it as a newer version, and it loaded it, checked it, then just went back to the bootloader screen like there was no image there at all. Last night I was thinking that if I pulled the internal battery (the little tiny one) then it would lose its info, allowing me to load any PC10IMG I wanted. NOPE. Rom and all its info and settings are still intact. Weird, cuz I thought that's what that little battery was for. So, I'm out of options. I love the rom, it's fast as hell and the battery life is far better than when I had my last G2. I just wanna overclock, add some sounds without using Zedge or something (want internal mods that arent dependant on memory using apps), and do some theming. Oh, and removing that horrible pink bloat >:]
I just know that our awesome Devs will come up with something.
XDA ROCKS!!!!!
Waiting?!
Any updates regarding the root?
I tried everything, and nothing works.
I even tried to resend it to the repair center to get froyo, they returned it back saying that they could no longer Downgrade it!
well this is my argument, you can call them and ask them for one that is froyo
complain to them that you have netflix and paying for a service to use on your phone reason why you got it, and since "THEY" updated and made it unsuably they are obligated to give you one that can use netflix or a replacement that can use it as they have done something that was not confirmed with you if you sent it for simple repair, you did not get your phone back to how it was you got something different...
start this fight you will probably end up with a mytouch 4g

Hi!
The config options that you would have to change are written to the emmc on partition17 (main version) or partition7 (S-OFF, SuperCID, SIM-Lock) so that will not change if you pull any kind of battery.
The only chance to root this rom is that we find a new temp-root method and then do the usual things (misc_version, goldcard, downgrade, gfree, ...)
I do not expect that someone publishes a new temp-root before either T-Mobile/HTC rolled out the OTA or a different device running 2.3.4 really needs it.
Have fun - Guhl

This thread has been made many many times. Check the threads, the wiki, etc.. There are ways to downgrade and achieve root now.
You can do it, but you have to use frevo and abd.

wow thats a good deal for the defy....
@martonikaj maybe you can help a dude out--i am not able to push the files to the device at all i keep getting permission denied in the command prompt and also if i do the downgrade(get it to work that means the radio has been downgraded as well)can i get that back because it really improved my signal in some areas where i had only 2g service i now get 4g--i read the wiki backwards and forwards although i broke my stock usb cable maybe this is the problem im using one that i picked up from the tmo store just the general one--i got adb and sdk all that jazz got a pretty good understanding for a noob so im kind of stuck...
